As PawPaw said, many pure and near pure lead bullets (swaged bullets usually have a percent or two of antimony anymore) get shot all the time. You just can't go for much pressure and velocity with them. There are several theories of optimum hardness of the bullet for the peak pressure of the load. For BHN 4.5 (pure lead) you generally want loads in black powder pressure ranges, and lower ones at that. But many light target loads qualify.
